The redbreast sunfish (Lepomis auritus) is a species of freshwater fish in the sunfish family (family Centrarchidae) of the order Perciformes. The type species of its genus, it is native to the river systems of eastern Canada and the United States. The redbreast sunfish reaches a maximum recorded length of about 30 centimetres (12 in).
The species prefers vegetated and rocky pools and lake margins for its habitat. Its diet can include insects, snails, and other small invertebrates. A panfish popular with anglers, the redbreast sunfish is also kept as an aquarium fish by hobbyists. Redbreast sunfish are usually caught with live bait such as nightcrawlers, crickets, grasshoppers, waxworms, or mealworms. They can also be caught using small lures or flies. Most anglers use light spinning tackle to catch redbreast sunfish. It is popular with fly anglers in the winter because it will more readily strike a moving fly than will bluegills in cooler water.
As is typical for the sunfishes, the female redbreast sunfish lays her eggs (about 1000) in a substrate depression built by the male. [2] The male guards the eggs and fry.
The specific epithet, auritus, is Latin for big-eared.
The average length of the redbreast sunfish is around 11 centimetres (4 in) with a record 30.5 centimetres (12.0 in). The record weight for the fish is 0.79 kilograms (1.7 lb). The redbreast sunfish is characterized by a long black opercular flap, which is longer than those of most other sunfish in its range. [3] There are a few blue iridescent vermiculations on the head. Small teeth may be appreciated, mostly on the roof of the mouth. [3] [4] There are faint vertical bars present on the olive-green bodies of both sexes, which may become more apparent as the background coloration changes to blue-green near the lateral line. [3] [5] Males have darker ventral coloration than that of females, ranging from orange-yellow to orange-red. [3] The caudal fin has a shallow fork and may have orange to red pigmentation. [3] It is common within the redbreast sunfish's native and introduced range for hybridization with other sunfish species to occur. [6]
The species' native range is in the eastern United States and Canada, in rivers emptying into the Atlantic Ocean. The redbreast sunfish tends to be more of a cool-river species, but also inhabits freshwater lakes and streams. The species has been introduced as far west as Louisiana and West Texas. [6] Lepomis auritus has been transplanted to and become established in Germany, Italy, [7] Mexico, [8] and Puerto Rico. [6] The effects of introduced populations of redbreast sunfish on native species are not well studied. [6]
Redbreast sunfish mainly consume immature aquatic insects. Mayflies, small fish, and dragonfly larvae consist of the majority of the sunfish's diet based on stomach content. Small crayfish may also be consumed. Being an opportunistic feeder, the fish competes with other sunfish and larger predatory fish that prey on the same food they do.
Larger piscivorous fish are the main predators of smaller redbreast sunfish. Micropterus species are a major threat to sunfish because of their shared habitat and the availability of the sunfish. The sunfish prefers structures around banks and overhanging branches that provide food, shade, and protection. Lepomis auritus survives best in water with a current and a pH between 7.0 and 7.5. [2] Lack of current, overly acidic, or basic water can dramatically affect the sunfish's survival rate.
Human influence on abiotic factors, such as sunlight, and biotic factors, such as predator numbers, can have a major influence on sunfish. Clearing debris from the bank can increase the amount of sunlight that reaches the water, thus increasing water temperature, while also decreasing the number of hiding places along the bank that sunfish can use. Decreasing the number of larger predatory fish by harvesting them will increase the survival rate of the redbreast sunfish.
The redbreast sunfish is a spring spawner on sand-gravel substrate, depending on location or when water temperature reaches 16–26 °C (61–79 °F). According to Stanley Sharp, "The mature male generally builds a nest in shallow water or may simply use the abandoned nest of another Centrarchid. The female eventually enters the nest, releases her adhesive eggs for fertilization while swimming with the male, and then leaves. The male remains to guard and fan the eggs, and possibly even to guard the young for a brief period. The male and female will then move out of the shallow water after spawning and into deeper water. A male sunfish will breed with more than one female, just as a female sunfish will breed with more than one male. Average egg production for the sunfish is around 3000, depending on the age of the female. [9] Mature ova are around 2.1 millimetres (0.083 in) in diameter. [9] Reproductive maturity is reached in the second year of life. They have been known to have a maximum lifespan of around eight years. [3] Currently, humans do not play a large role in influencing life history due to large populations and secluded areas.
Currently, the redbreast sunfish is not on the federal or state endangered or threatened species list. The species is thriving in its natural habitat.
The IGFA all tackle world record for the species stands at 0.79 kilograms (1 lb 12 oz) caught from the Suwannee River in Florida in 1984. [10] A Georgia state record fish caught in the Satilla River in May 2022 tied the world record. [10] [11] A North Carolina state record fish caught on the Lumber River in 2019 weighed 2 pounds 1 ounce (0.94 kg). [12]
Centrarchidae, better known as sunfishes, is a family of freshwater ray-finned fish belonging to the order Perciformes, native only to North America. There are eight universally included genera within the centrarchid family: Lepomis, Micropterus, Pomoxis (crappies), Enneacanthus, Centrarchus, Archoplites, Ambloplites, and Acantharchus. A genetic study in 2012 suggests that the highly distinct pygmy sunfishes of the genus Elassoma are also centrarchids.
Crappies are two species of North American freshwater fish of the genus Pomoxis in the family Centrarchidae (sunfishes). Both species of crappies are popular game fish among recreational anglers.
The bluegill, sometimes referred to as "bream", "brim", "sunny", or, as is common in Texas, "copper nose", is a species of North American freshwater fish, native to and commonly found in streams, rivers, lakes, ponds and wetlands east of the Rocky Mountains. It is the type species of the genus Lepomis, from the family Centrarchidae in the order Perciformes.
The word panfish, also spelled pan-fish or pan fish, is an American English term describing any edible freshwater fish that usually do not outgrow the size of an average frying pan. It is also commonly used by recreational anglers to refer to any small game fish that can fit wholly into a pan for cooking but are still large enough to be legal. According to the Oxford English Dictionary, the term was first recorded in 1796 in American Cookery, the first known cookbook written by an American author.
Lepomis or true sunfish is a genus of North American freshwater fish from the family Centrarchidae in the order Perciformes. The generic name Lepomis derives from the Greek λεπίς ("scale") and πῶμα. The genus' most recognizable type species is perhaps the bluegill.

It is closely related, and morphologically similar to the European perch ; and is sometimes considered a subspecies of its European counterpart.
The green sunfish is a species of aggressive freshwater fish in the sunfish family (Centrarchidae) of order Perciformes. A panfish popular with anglers, the green sunfish is also kept as an aquarium fish by hobbyists, they need a 55-75 gallon tank and can be fed minnows, mealworms, or nightcrawlers. They are usually caught by accident, while fishing for other game fish. Green sunfish can be caught with live bait, such as nightcrawlers, waxworms, mealworms, and blood worms. Grocery store baits, such as pieces of hot dog or corn kernels, can even catch fish. Green sunfish are aggressive and will hit small lures. They can be caught with fly fishing tackle. They are extremely aggressive and will attack swimmers. They usually get 10 inches long, but in some cases they can get 12 inches long.
The longear sunfish is a freshwater fish in the sunfish family, Centrarchidae, of order Perciformes. It is native to the area of eastern North America stretching from the Great Lakes down to northeastern Mexico. The longear sunfish reaches a maximum recorded length of about 24 cm (9.4 in), with a maximum recorded weight of 790 g (1.74 lb). Most do not live beyond six years. The longear sunfish is quite colorful, with an olive to rusty-brown back, bright orange belly and vermiculate blue-green bars on the sides of its head, the latter two features most pronounced in breeding males. A unique characteristic of longear sunfish is their elongated operculum flap, giving an appearance of a "long ear". It is black and often has a white margin. The pectoral fin is relatively short and would not reach the snout if it were reflected anteriorly. In breeding males, iridescent blue spots develop on the dorsum and sides and the fin membranes turn orange in all fins except the ventral ones, which may be blue to black, and the pectoral ones. Lepomis megalotis can be distinguished from closely related dollar sunfish L. marginatus by a greater number of cheek scale rows, by having one to two additional pectoral fin rays and by the slope of the opercular flap, which is distinctly upward in L. marginatus but is closer to horizontal in males of L. megalotis, although female and subadult L. megalotis may have upward slanting opercular flaps.
The redear sunfish, also known as the shellcracker, Georgia bream, cherry gill, chinquapin, improved bream, rouge ear sunfish and sun perch) is a freshwater fish in the family Centrarchidae and is native to the southeastern United States. Since it is a popular sport fish, it has been introduced to bodies of water all over North America. It is known for its diet of mollusks and snails.
The spotted sunfish, also known as a stumpknocker, is a member of the freshwater sunfish family Centrarchidae and order perciformes. The redspotted sunfish, redear sunfish and pumpkinseed sunfish are its closest relatives. Lepomis punctatus is olive-green to brown in color with black to reddish spots at the base of each scale that form rows of dots on the side. The scientific name punctatus refers to this spotted pattern. It was first described in 1831 by Valenciennes.
The dollar sunfish is a species of freshwater fish in the sunfish family of order Perciformes. It is categorized as a warm water pan-fish. Early settlers said that this species of sunfish resembled a European species they called bream. Historically it has been found along the Southern Atlantic coastal drainages from North Carolina to Florida, and west to Texas. Lepomis marginatus mainly feeds on detritus and filamentous algae as well as a few terrestrial insects. The juvenile and mature fish do not have many predators, but the eggs in the nest are in danger of predation from a few different species of fish.
The redspotted sunfish, also known as a stumpknocker, is a species of freshwater ray-finned fish, a sunfish from the family Centrarchidae which is native to the United States. The redspotted sunfish was previously considered to be a western subspecies of spotted sunfish but was distinguished as a separate species by Warren in 1992.
